Millie Bobby Brown's reaction to the wrapping of 'Stranger Things' season three

Saying goodbye to Eleven, Will and Max is breaking Millie Bobby Brown's heart.

On Monday, the 14-year-old Stranger Thingsactress posted some emotional Instagram Stories as she finished filming the wildly popular show’s third season — leading fans to speculate that this might be the sci-f series’ final run.

Initially, Millie shared a video in a car explaining that she was going to “cry all day fyi” on the last day of shooting. She also wrote individual messages to costars Sadie Sink, who joined the second season as Max Mayfield — “I can’t say good-bye” — andNoah Schnapp, who plays Will Byers — “this is not okay.”

Her sentimental captions had viewers wondering if it was the last day of filming for good. In February,rumors circulated that the Duffer brothers, the creators and primary showrunners, were to leaving after the third season. But Netflix has since refuted those claims.
